Title: Oxidation of olefin
Inventor: KIYOURA TADAMITSU
IPC: C07C5/333
Filed: 1982-06-08
Abstract: PURPOSE:To carry out the oxidation of a 4C fraction, etc. in high efficiency, by using a catalyst prepared by adding antimony oxide and/or thallium oxide to a catalyst composed mainly of molybdenum and used for the preparation of acrylonitrile by the ammoxidation of propylene.

Abstract: PURPOSE:To attain highly accurate positioning characteristic of optical spot and thereby to accomplish an excellent recording and reproducing characteristic by disposing the center of gravity of a moving part on the line of action of the axial-directional driving force of a driving source and thereby preventing an occurrence of couple due to vibrate in the axial direction. CONSTITUTION:The titled device is provided with a moving part having a base 14 supported slidably in the axial direction of a slide shaft 3 and rockably around the shaft of the shaft 3 and an objective lens 2 fixed to the base 14 apart from the shaft 3, and a moving part which comprises an objective lens fixed on the base 14 apart from the shaft 3 as well as a stationary part having a driving source which drives the moving part in the axial direction and around the shaft. The center of gravity G of the moving part is disposed on the line of action of the axial-directional driving force of the driving source. Therefore, no couple of force arises even if vibration occurs in the axial direction. Accordingly, the moving part is suppressed of inclining due to the couple. In result, the positioning characteristic of optical spot is improved.
